October 23, 2012 C-1981-008/New Horizon Mine MLT
BACKFILL and GRADING—Rule 4.14
Contemporaneous Reclamation 4.14.1; Approximate Original Contour 4.14.2; Highwall
Elimination 4.14.1(2)(f); Steep Slopes 4.14.2, 4.27; Handling of Acid and Toxic Materials
4.14.3; Stabilization of Rills and Gullies 4.14.6:
• Backfilling of the final pit on the Morgan property was continuing; the pit is being filled
from south to north. Overburden material was being hauled to this location by the mine's
fleet of three haul trucks. The trucks backed up to the south end of the remaining pit and
dumped their loads down the slope (Photo 1). A bulldozer then worked to push the material
down into the pit.
• I asked Mr. Gubka if the bulldozer was pushing and compacting the material all the way
down into the pit, and he said no, the dozer was not going that far down. I reiterated the
Division's concern that the lack of compactive effort being applied to the lower portions of
the fill may contribute to future differential settlement of the reclaimed field.
• Mr. Gubka said the dewatering pump was working to pump out the water displaced by the
backfilled material, to keep the water level in the pit from rising.
EXPLOSIVES —Rule 4.08
Distance Prohibitions 4.08.4; Warnings 4.08.4; Control of Adverse Effects 4.08.4:
• The drill rig was idled during the time of the inspection. The most recent blast, according to
the mine's records, occurred on October 17, 2012.
FISH and WILDLIFE—Rule 4.18:
• A large number of Canada geese were gathered on the water and shoreline of Pond 007
(Photo 2).
• A dozen or so ducks were seen on the shallow water in Pond 011.
HYDROLOGIC BALANCE -Rule 4.05
Drainage Control 4.05.1, 4.05.2, 4.05.3; Siltation Structures 4.05.5, 4.05.6; Discharge Structures
4.05.7, 4.05.10; Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13;
Surface Water Monitoring 4.05.13; Drainage—Acid and Toxic Materials 4.05.8; Impoundments
4.05.6, 4.05.9; Stream Buffer Zones 4.05.18:
• The ground and surrounding area is extremely dry. The CCC Ditch has been shut off for the
season, although a"pond run" to fill all of the stock ponds before winter is typically made in
late November, and will likely take place this year.
• Pond 007: WFC has recently pumped water from this pond to lower the volume for the
winter. No discharge was occurring at the time of the inspection (Photo 3). Tamarisk plants
have been cut from the portion of the pond south of 5th Road, and the inslopes appeared to
be stable and reasonably well vegetated.
